An arbitrary file upload vulnerability, dubbed CVE-2024-34982, has been discovered in the component /include/file.php of lylme_spage v1.9.5, which allows attackers to upload and execute arbitrary code on the targeted server by uploading a crafted file. This is a severe issue as it poses a significant risk to businesses or individuals using the affected software.

In this detailed post, we will discuss the vulnerability, share code snippets to demonstrate how it could be exploited, and provide links to original references for further reading.

Vulnerability Details

The arbitrary file upload vulnerability in lylme_spage v1.9.5 resides in the /include/file.php component. When exploited, it enables an attacker to upload and execute a crafted file that contains malicious code. This could have severe consequences, including unauthorized access and control of the targeted server, theft or destruction of sensitive information, and disruption of regular operations.

The root cause of the vulnerability is inadequate input validation, leading to improper handling of user-supplied data. Additionally, there is no proper authentication required to access the affected component, making it easily exploitable by any malicious user.

Exploit Details

To exploit the vulnerability, an attacker needs to create a crafted file that contains malicious PHP code. This can be done using any text editor, such as Notepad++. Here's an example of a simple PHP file containing malicious code:

<?php
  echo "This is a test of the CVE-2024-34982 exploit!";
  // You can add any arbitrary code here, for example:
  // - Execute a shell command
  // - Write or delete files on the server
  // - Exfiltrate sensitive data
?>

Once the crafted file has been created, the attacker can then target the /include/file.php component of lylme_spage v1.9.5 to upload the malicious file. This can be done using a simple CURL command or more advanced tools, such as Burp Suite or Postman:

curl -X POST -H "Content-Type: multipart/form-data" -F "file=@/path/to/crafted_file.php" http://example.com/include/file.php

Replace /path/to/crafted_file.php with the location of the crafted file on the attacker's machine, and replace example.com with the URL of the targeted server running lylme_spage v1.9.5.

Upon successful exploitation, the malicious file will be uploaded to the server, enabling the attacker to execute arbitrary code to carry out further malicious activities. This may include creating backdoors, accessing sensitive data, modifying server configurations, or launching attacks on other systems.
